Number type to small for TickInterval, month

Feb 16, 2015 at 1:06 PM
I am trying to set TickInterval to month by setting:

TickInterval = 7 * 24 * 3600 * 1000 * 30

the tickInterval is an signed int and can not contain this value
week is ok with TickInterval = 7 * 24 * 3600 * 1000

Is there any way around this?
